Glitchy sound from OX

Listen to sound sample here or attached file: https://drive.google.com/file/d/13XEOkVcSJV-PysFh_n297nIFIt9gfLqE/view?usp=share_link - clean sound at first. With drive activated, the issue begins

My OX is imparting a strange glitch like sound over my guitar signal. I am using a guitar with P90s, a 64 fender bassman head, and a 1x12 Blue amp sim. This happens when I turn a drive pedal up, or a fuzz. I am not clipping the signal anywhere. It is definitely not what the pedal is supposed to sound like. Sample rate on my Apollo is 44k. There is also a feedback sound in the clip when I move the guitar near the OX, but I feel like that's inevitable. Can anyone help me figure this out? I've rebooted the OX several times, have updated firmware, and the issue still persists.

This all sounds perfectly normal to me.

See here for more:

With OX, you're hearing your amp "for the first" again. So expect to re-work how you like the amp and pedals to be set.

This is not normal whatsoever. It is unlike any distortion I've ever heard let alone what I know I've heard from my OX before. There is a phase/flange sound caused by high gain. Ive attached another file that is more clear. Clean sound at first, then pedal engaged. I also try two different dirt pedals in this sample and both produce the same issue.

I opened a ticket yesterday. You would agree something is not quite right here? I've never had this issue. Have run countless high gain pedals into my amp>OX with no issue.

Without being there, and having heard your previous attempts, there is no way to really tell.

You're driving that pedal quite hard, so I'm not surprised by anything I am hearing.

I am quite surprised by that response. My amp has plenty of headroom already, and it is just a simple distortion pedal, nothing crazy high volume. I am not clipping the signal anywhere into the OX either.

I don't know the pedal nor how it's set. But I can tell it's driving the signal A LOT. Without being there, it's really tough to say anything definitely.

W/o being there and hearing what it sounded like before it's almost impossible to diagnose.
I have a genuine 1964 Bassman amp too. Outstanding piece of kit.
The overdriven tone in the sample sounds to me (w/o being there) like an amp collapsing in on itself from too much input gain. Or, a maxed-out fuzz pedal. Or a speaker that's being pushed really hard. Or all of the above.
Did you record that via a DAW? I hear some 'clean' signal along with the OD tone.

It was recorded into LUNA yes. This sound is also happening through headphones plugged into the OX. I am not clipping anywhere. Id never have this issue just hearing my amp through a cab. It is definitely something going on in the OX

First question. When you say you never have this issue with the amp through a cab, do you mean the OX is not connected in between the amp and the speaker cab? If you have the OX connected (using as attenuator), my findings below are probably not whats causing your noise issues.

The sound clip you shared is indeed not normal. I have the OX box and experienced recently some weird noises coming from my connected 8 Ohm speaker cab connected with the OX box and I think it had something to do with the OX speaker impedance relais switch or OX amp input. Gently switch back and forth between the 4, 8, 16 Ohm setting (hear the internal clicking of the relais) and also unplug and plugin the speaker cable a view times which is coming from your amp speaker output to the OX amp input might help restoring a proper electrical connection.

I don't think its a software DSP issue but maybe some oxidation on your speaker cable jack plugs, OX amp input or the relais. Not saying it's the same problem but something you could try. After I done some clicking with the OX impedance switch, cleaning the input and jack plugs the weird noise problem is gone. So the problem for me was a bad connection, maybe from humidity or dust.

I will give this a try, thanks. Without the amp on of course!

Your welcome. Amp off, OX on so the relais is working.

If you have a cable tester you could test the speaker cable as well.

I just tried this and even more worrying issue came up. The switching between ohm rating was not working properly. It was creating multiple clicks and indications that the relay switch was having problems. I run my amp at 4ohm and im worried it wasnt actually at 4ohm this whole time. I found the switch to indicate finally that it was safely back at 4ohm, but the issue still persists. Tried unplugging and plugging in the speaker cable as well. Switched sides of speaker cable, same issue.
